Isabelle Aubert

Isabelle Aubert is a Canadian neuroscientist with expertise in developing regenerative therapies for neurodegenerative disorders (including Alzheimer's disease). She is a senior scientist at Sunnybrook Research Institute (where she leads Sunnybrook's Brain Repair Group), and is a professor in laboratory medicine and pathobiology at the University of Toronto. In 2019, Aubert was appointed as a Canada Research Chair (Tier 1) in Brain Repair and Regeneration.

Research Aubert's research involves developing treatments to protect and repair the brain after illness or injury, including a novel gene therapy to reprogram brain cells, and using low-intensity focused ultrasound guided by MRI to bypass the blood-brain barrier and deliver therapeutics to specific areas of the brain. The latter is a minimally invasive technique, where using MRI to visualize target areas in the brain, microbubbles are injected into the bloodstream. Aubert's lab has also demonstrated that MRI-guided focused ultrasound can be used to deliver the D3 molecule (a growth factor-related therapeutic) to cholinergic neurons (memory-related brain cells, which are vulnerable in Alzheimer's disease) into the brains of mice with Alzheimer's disease.

Aubert has published over 150 academic publications, which have been cited over 6,000 times, resulting in an h-index and i10-index of 36 and 63 respectively. In 2019, Aubert received a $100,000 one-year grant from the Canadian Institutes of Health Research to "explore the use of genetic engineering of brain cells so that they can make antibodies against the toxic proteins related to the pathology of Alzheimer's disease."
